Reset Output. Configurable, active-low, open drain, or weak pullup. RESET assumes its
programmed conditional output state when V
Watchdog Timer Output. Configurable, active-low, open drain, or weak pullup. WDO
asserts when WDI is not toggled with a valid high-to-low or low-to-high transition within
the watchdog timeout period.
Undervoltage/Overvoltage Output. Configurable, active-low, open drain, or weak pullup.
UV/OV assumes its programmed conditional output state when V
(2.5V).
Ground
Watchdog Timer Input. Logic input for the watchdog timer function. If WDI is not toggled
with a valid low-to-high or high-to-low transition within the watchdog timeout period,
WDO asserts. Progam initial and normal watchdog timeout periods from 6.25ms to
102.4s. WDI is internally pulled down to GND through a 10µA current sink.
Manual Reset Input. Program MR to assert RESET and/or UV/OV when MR is asserted.
Leave MR unconnected or connect to DBP if unused. MR is internally pulled up to DBP
through a 10µA current source.
